MILK-JAR CLOSURE OR CAP.

SPECIFICATION forming part of Letters Patent No. 761,005, dated May 24, 1904.

Application filed July 14, 1902. Serial No. 115,537. (No model.)

To all whom it may concern.-

Be it known that 1, DAVID PELTON MOORE, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Milk-Jar Closures or Caps, of which the following is a specification.

This invention relates to improvements in milk-jar closures or caps; and the main object of my invention is to provide a cap which is made of a flexible and absorbent material, such as paper, and is provided with integral means for removing the closure from the mouth of the jar at pleasure, the said means being of such a thickness that it will not cause the cap to bulge where it contacts the mouth of the jaw or bottle. By making the cap concave in cross-section and of absorbent mate rial it will as it absorbs moisture from the milk slightly expand and cause its peripheral rim to more tightly engage the groove formed in the inner mouth of the milk-bottle, thereby sealing the mouth of the bottle. It will also be noticed in this formation that the cap will be braced by its peripheral" rim against the jars groove and will withstand a pressure from below, so as not to be easily forced from engagement with the mouth of the bottle. To attain these objects, the invention consists of a jar or bottle closure embodying novel features of construction, substantially as disclosed herein.

In the accompanying drawings, Figure 1 is a transverse sectional View of the upper neck of the milk-jar with my improved cap fitting therein. Fig. 2 is atop plan view of the cap with the integral handle shown in use in full and in blank as in dotted lines.

The closure, as shown in Figs. 1 and 2, consists of the circular disk 1, whose body is slightly concaved in cross-section and terminates in the upwardly-inclined peripheral rim 2. This disk is formed in this shape by means of a die and is provided with the peripheral flap 3, which is pressed to a thickness of about one-half of that of the body of the disk to form the connecting-strip 4 and the handle or tag 5, said connecting-strip 4 being attached to the top of the disk by means of a staple or fastening 6. The flap orhand'le is of greater width than the strip 4:, so as to provide a better surface to grasp the same to remove the disk from engagement with the interior groove 7 of the milk-jar.

This invention has been especially designed to overcome objections to the closures now in use and also to cheapen the manufacture of a closure which can be readily attached or detached from the milkjar. The handle, as shown, is so formed with the body of the disk that it allows the rim of the disk to snugly and neatly engage the internal groove of the milk-jar, thus preventing the disk from bulging, as is the case with all other disks employing extra handles or flaps.

The handle or flap herein shown is formed either by stamping or molding directly from the body of the cap or closure simultaneous with the forming of the concaving of the cap or closure, thus reducing the amount of material and cost of manufacture and rendering u a thoroughly efficient closure. It will also be noted that when this closure is formed any advertisement which may be necessary to be placed thereon may be either printed or pressed at the same time with the forming of the closure.

What I claim as new is 1. A jar closure or cap, comprising a disk having an integral flap formed upon one edge thereof and compressed to a smaller thickness than the body of the disk to form a handle for the cap.

2. A jar closure or cap comprising a disk of absorbent material, and an integral flap formed upon one edge of the disk and compressed to a smaller thickness than the body of the disk, said flap being bent inward and upward, and means for securing the flap at the junction of the upwardly-bending end thereof. v

3. A jar closure or cap comprising a circular disk made concaved in cross-section, a flap formed from the body thereof and compressed to a thickness thinner than that of the body of the disk, said flap being bent inward to form a substantially L- shaped flap in cross-section and a staple to secure the flap at the angleof the L to the disk.

A. A jar closure or cap comprising a cir- I cular disk made concave in cross-section, a flap formed from the body thereof near the periphery and compressed to a thickness thinner than that of the body .of the disk, said flap being bent inwardly and upwardly, and means for securing the body of the flap at its angle to the body of the disk.

5. A jar closure or cap, comprising a circular disk made concave in cross-section, a flap formed from the body thereof near the periphery and compressed'to a thickness thinner than that of the body of the disk, said flap being bent inwardly and upwardly, and a staple for securing the body of the flap at its angle to the body of the disk.

6. A jar closure or cap, comprising a disk made of absorbent material and an integral flap formed upon the circumferential edge thereof and compressed to a lesser thickness than the body of the disk so as not to project beyond the circumferential edge ofthe disk, said flap being bent inward from the circumferential edge of the disk and then upward, and means for securing the flap at its junction with the upwardly bent portion to the body of the disk;

- 7. A jar closure or cap comprising a disk ,made of absorbent material and an integral flap formed upon the circumferential edge thereof and compressed to a lesser thickness than the body of the disk so as not to project beyond the circumferential edge of the disk, said flap being bent inward from the circumferential edge of the disk and then upward, and a staple for securing the flap at its junction with the upwardly-bent portion, to the body of the disk.

In testimony whereof I aflix my signature in presence of two witnesses.

DAVID PELTON MOORE.
